Fig. 226 is the reproduction of a transverse section of a young cystocarp. An- theridial plants were not found. Some of the specimens had tetrasporangia. These occured at the base of the ramuli, one to three growing out from each bark-ring. This species is very common along the shores of the islands. Geogr.

This plant (Fig. 227) is originally described from a specimen from St. Thomas which KüTziNG received from Senator Binder. The description below is based upon specimens collected by me, not only at St. Thomas, but also at St. Croix. The thallus is terete. The ramification is distichous, both the branchlets and the ramuli issuing seriate from both sides of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dansk botanisk forening.
